Scientists have taken a big step closer to answering that question by pinpointing the genes responsible for tail regeneration. And the finding may yield important clues about how to regenerate limbs in humans.

For the study, the researchers took a close look at roughly 23,000 genes found in samples of sliced-up tails of green anole lizards. They found that at least 326 genes in specific spots along each tail were "turned on" during regeneration -- suggesting that lizard DNA has a genetic "recipe" for rege...
